1.06 Ct. Purplish Red Ruby from Burma (Myanmar)

This ruby is a transparent cushion shaped purplish red gem weighing 1.06 carat, with precise measurements of 6.13 by 5.90 by 3.09 millimeters, presented in a mixed brilliant cut that marries the scintillation of brilliant facets with the depth provided by step facets. The stone carries a clarity grade of included when evaluated at eye level, which in natural rubies often manifests as fine crystals or silk like inclusions that are part of the gemstone story rather than imperfections to be feared. The color intensity is described as dark, which imparts a rich, saturated appearance that reads as purplish red and benefits from deeper pavilion facets that concentrate color. The polish is excellent, and the stone is unenhanced, with no heat treatment or other enhancement reported, a trait that materially affects market value and desirability. The origin is Burma Myanmar, a provenance long associated with premium rubies, and this provenance combined with the untreated status makes the piece especially significant to collectors and connoisseurs. The Natural Ruby Company presents this gem as an example of classic Burmese character together with gem cutting and finishing that respect the material.

When discussing grading and clarity it is important to place the included grade in context, inclusions in rubies are common and are often part of how gemologists determine natural origin and treatment history. Inclusions visible to the unaided eye indicate a window into the crystal, and in Burmese rubies such features can include rutile silk, pinpoint crystals, and healed fissures. These features can diffuse light in beneficial ways, creating a velvety or soft glow that enhances color saturation and can reduce harsh reflections. The dark color intensity here implies a higher tone with strong saturation, which for many buyers translates into a visually powerful and elegant stone rather than a pastel or washed out tone. The mixed brilliant cut serves a dual purpose, maximizing face up brilliance on the crown with brilliant facets, while the pavilion and step components deepen the perceived color and add a layered complexity to light performance. Excellent polish ensures that facets meet cleanly and reflect light efficiently, which is a crucial factor when evaluating sparkle and overall finish.

Optical performance changes with ambient lighting, and this ruby displays a dynamic personality across different illumination conditions. In natural daylight, particularly in northern or indirect daylight, the purplish red character will appear lively, with the mixed brilliant facets delivering scintillation and the step facets providing color saturation. Under warm incandescent lighting the stone will read warmer and redder, the deep tone taking on a richer crimson presence that can appear more luxurious and intense. Under modern LED lighting which varies by color temperature, cooler LED sources will emphasize the purplish component and may yield a slightly cooler red, while warm LED sources will mimic incandescent behavior. Fluorescent light can sometimes flatten color slightly for darker stones, but the excellent polish and facet design in this ruby counteract that tendency, maintaining noticeable sparkle and depth. In low light and candlelight the stone will show strong color saturation and a subdued glow rather than overt sparkle, which many collectors prefer for evening wear because it conveys depth and presence. The stone also displays pleochroic tendencies typical of corundum, meaning that slight changes in viewing angle or rotation in the setting will reveal shifts between more red and more purple notes, adding life and complexity to the gem.

For the educated buyer the combination of factors that this ruby presents creates a compelling value proposition. Burmese origin has long been prized for the unique trace element profile and the classical tonal beauty associated with the region. An untreated ruby from Burma is uncommon relative to heat treated stones, and that untreated status is a strong premium attribute in the market. The included clarity grade should be read as characteristic rather than defective, and the particular types of inclusions commonly found in Burmese stones often corroborate a natural, unheated history. The cushion shape and mixed brilliant cut make the gem versatile for high end jewelry applications, and the dimensions and cut proportions in this specimen allow for secure settings that protect the stone while showcasing its face up color. Corundum rates 9 on the Mohs hardness scale, which provides excellent durability for everyday wear in rings, pendants, and other pieces, provided the setting offers protection to the girdle and corners. The excellent polish will preserve surface brightness and make routine cleaning highly effective. The Natural Ruby Company stands behind the provenance and the description of this ruby, and we encourage in person viewing or high resolution imaging for final assessment. For purchasers seeking an authentic Burmese ruby that is untreated, darkly saturated, and cut to balance brilliance and color, this 1.06 carat cushion purplish red ruby represents a meaningful acquisition that combines historical desirability with transparent gemological detail.
